1 out of 100,000 ? I've read and heard people are talking of 4-5% failure rate. So out of 100,000 it would be 5000 with bad fd or input shaft. I for one had an 04 rt, fine bike and must say better looking than my 06 st, but hearing about those failures made me weary. After all I don't want to look at the bike parked, I want to ride knowing it'll bring me back home. To replace input shaft is not an easy task and for a dealer to do it is around $2500 +/- $500. I just do not have that kind of money laying around for that, not that it would happen, but just in case. Also some recommend lubing that shaft every 30k-40k miles. Again, $$$. ST on the other hand, reputation is second to none, seems that everything japaneese is. Gearbox on a st is so much smoother, on a beemer I had few issues going from say 4th and down. ST, never heard of fd or input shaft go bed, maybe some heat issues, if that's all they rave about, I'll take it. As far as heat, you don't think rt gets hot, think again. I got stock in bumper to bumper traffic on a 85 deg. day and believe me I was cooking. Basically waht is coming down to, you will spend initially more $$$ buying BMW and mainetance as well. One thing I have to say, RT being a little lighter felt like it handled better, not by much but it did.
